Hvem daterte Samuel Diescher?

Samuel Diescher (June 25, 1839 – December 24, 1915) was a prominent Hungarian-American civil and mechanical engineer who had his career in the United States. After being educated at universities in Karlsruhe and Zurich in Europe, he immigrated to the United States in 1866 and settled in Cincinnati, Ohio. There he supervised construction of his first inclined plane. He later moved to Pittsburgh, Pennsylvania, where he worked with John Endres on the Monongahela Incline (1870), the first passenger incline in the city.

Diescher designed the Duquesne Incline (1877). He is believed to have designed the majority of inclined planes in the United States, including numerous projects in Pennsylvania. He also designed a wide range of industrial projects, particularly those related to the coal and steel industries. His three sons also became engineers and in 1901 he set up a business with them: S. Diescher and Sons. These two early inclines in Pittsburgh are the only passenger inclines still in use there. Both are listed on the National Register of Historic Places and, in 1977, were also designated as Historic Mechanical Engineering Landmarks by the American Society of Mechanical Engineers.

John J. Endres was a civil engineer known for designing the Monongahela Incline, the first passenger incline in the United States, in Pittsburgh, Pennsylvania. The incline was originally steam powered and ran on wooden tracks. Born in Prussia and educated in Europe, Endres had immigrated to the United States and settled in Cincinnati, Ohio. His daughter, Caroline Endres, born and educated in the US, became one of the first women engineers in the country. She assisted him on the Monongahela Incline.

While the two were working in Pittsburgh, they met fellow engineer Samuel Diescher, who was born in Hungary and had immigrated to the US in 1866. Diescher and John Endres became friends and business partners. Samuel and Caroline married in 1872, and resided in Pittsburgh. They had six children together, including three sons who became engineers and went into business with their father.

Endres returned to Cincinnati after constructing the Monongahela Incline. He returned to Pittsburgh in 1883 to help Diescher design the Monongahela Freight Incline, completed the following year.
